.To all whom it yneay concern:

Be it known am I, snscsa ons, s unimi of the United States, residingstChicago, Iliinoie, have invented certain new and useful 5 Improvementsin Dump- Camel which the following isa specitication. i

This invention relates to that classe! cars lknown ns dnmpcarsthst is,cars pro- `vided with s supporting frame kportion and e dumping bottomportion through which loose bulky freight, such as cosi and similarelements,msyheeasil dischargedand rticii larly to the means ywhicli thedump ng bote tom portions sre heid in closed position in `:5 connectionwith 4tlie `supporting frame porg tion, all of which wiii'more fullyhereinafter sp r.

l l e-prlucipslobjectot this inventionisto Y gcvide s simple,economical, and eilicient o' `ttoiii dumping csr.y

`A further objectof the invention is to pro vide a dump-car having dropordumpingbotmechenisni'by which the door is held in po- 5 sitios andsealed when the parte are in closed position, ell ot which will morefully hereinafter appear. i

The `invention. consists principally in a. dumping bottom carin whichthere are come bined s supporting frame portion,V dumping bottomportions forming s list iioor ot the car provided with a groove orgrooves at or and neer the trame ot the csr arranged to engage the y vesin the edges of the csrdoor, so es to eip position and seal thejointibetween the same, substantially as hereinafter set forth. f

Theinvention consists, further end finally, in the features,combinations, and details of construction hereinafter described sudclaimed.

In the accompanying drawings, Figure 1 is n transverse verticalsectional elevation of n dninpcsr as it appears when constructed inaccordance with theseimprovements; Fig- 2, s plsu view of n Section ofthe car-bottom looking et it from above; Fig. 3, a sectional elevationof n portion .of line 3 o! Fig. 2lookingin the direction ol the 5 WWW;and Fig. 4 s detail pien view of c n 'toms with simple, economical, andemcient4 tsfree edges, and depending tongues in the csr, teken on4sigues sur reif-y s. iena. anni l. naiss. is mi ot the doors which formsthe dumping bottom portion of thecar.

In illustrating and describing these im-` provements I have onlyillustrated and will describe thst which I consider to be new, 55 takenin connection with'so much es is old as will pro rly disclose theinvention to others and ens le those skilled in the art tc practice thesame, leaving out of consideration other and well'known mechanisms,which if set forth hereinwould only tend to confusion, proiixity, andambiguity.

In constructing a car in accordance with these yimprovements I vinsite asupportingl framework having a plurality of center sills 65 a, towhichthe usual 'draft-timber b may be secured, s plurality oi'` deck-beams c,transvereely arranged, and side and end 'doors d andi',ex'tendingnpwsrdly from such framewor To sssistin carrying the load, aswell es in automatically discharging the samewhen the desired bulkyfreight is being transported, I make s bottoindumping portionforiiied ofs plurality of swinging doors f, pivotally'secured at their inner ed esto the framework, referably the center si ls, nt` each side of theongitndinsl center of the csr, so that they swing from the side boardsdownwardly end inwardly to discharge the load outside of the certrecks,all of which is desirable in many ceses. r

Itis often necesssry tohsve menne by which these doors may be positionedwhen in their closed position and the joint between such Idoors and thecar-frame sealed, so ne to prevent the leakage of line materials, suolies grain, sand, or the like. 1n order to provide such means, each ofsuch doors or swinging portion is provided with e groove or grooves g onthe three free edges thereofthat is, the front and both side edges-whilethe rear portion of such door is provided with en up4wnrdiy-extendiugtoiigue h. Thelongitudinel inverted-V-shapeii portion,-torming n cap 'and covering. for the center sills and s joint betweenthe pivoted ends of the' door end auch center sills, the inclined sideso! which central portion ol the cai' is provided with en ,95

which the doors are when in their open position, all of which tends toeiectually dischrge'the load. vTheIo'weredges of this`in`verted-V-shaped .portion are 'grooved, as at-j, so that theupwardly-extending tongues or flanges on the door may operate in thesame, all ot which tends to seal the joint between the V-shaped 'portionand the rear edge of the door and prevent the leakage of material xotherebetween.

To assist in positioning the door, as well asflanges thereof may rest inthe grooves inthe' free lateral edges of the s'winging'doors'or .bottom.'portions, thereby positioning the A z'o same as well as assisting insealing the joint between the doors and the car-frame.

To open and close the swinging doors or bottom portions, each side ofthe car is pro vided with a rock-shaft l, and each rock-shaf t 25 has a.plurality of chains n, engaging therewith and with the outer free endsof the door.

so that as such rock-shafts are rotated in one direction the chains arewound therearound and the .doors closed, and when such rock- 3oshaftsare rotated or permitted to wind in the opposite direction thechains are unwoun-d and the doors allowed to drop to their dumpingposition.

I claim- 35 1. In a car of the class described, the combination of a.supporting frame portion, dumping bottom portions'forming a flat floorof the car and, provided with a groove or grooves at or near its freeedges, anddepend- 4-ing tongues in the frame of the car arranged toengage the grooves in the edges of the cary door so as to help positionand seal the joint' between the same, substantially as described. 2. Ina car of the class described, the com'- 45 -binaton of a'supportingfran1ework, a plurality of dumping bottom portions pivotallysecured to each side of the longitudinal center of the car at theirinner edges and provided wth a groove or grooves around three 5o Afreeedges of such doors, and depending tongue mechanism on the car-framearranged to engage the groove mechanism of the door to assist inpositioning such door and sealing` the joint between it and the frame,substan- 55 'tiallyas described.

3. In a car of the class described, the comhinstion of asupporting-frame provided Ywith Jpwardly-extending side and end boards,a

dumpingbotto'm portion formed of a plurah'l ity of swinging doorsarranged along each side and longitudinally of the car pivoted at ltheirinner enges to the frameworkof the car and provided with a groove orgrooves at or near the three free edges of such door and anupwardly-extending tongue at or near their inner-edges, an A-shaped caparranged ioni gitndinally of the car-frame so as to 4span thelongitudinal center thereof above the dumping bottom portions attheirinner edges and provided with a. groove or grooves in which theupwardly-extending tongues of the swinging bottom portions operate, anddepending' tongue mechanism engaging with the grooves i Ain thecar-doors'to assist in positioning such doors and in sealing Ithe jointbetween thc sameand the frame of the car, substantially as described. l

4. In a car of the class described, the combiuation of asupporting-frame provided .with upwardly-extending side and end boards,a E dumping bottom portion formed of a plurality.of swinging doorsarranged along each side and longitudinally of the car pivoted at andprovided witha groove or grooves at or 8 near the three free edges ofsuch door and an upwardly-extending tongue at or near their inner edges,an A-shaped cap arranged longitudinall)r of the car-frame'sofas to span'the longitudinal center thereof above the dnmp 9 ing bottom. portions attheir inner edges and provided with a groove or grooves'in which thenpwardlyfestending tongues of the swing-w ing bottom portions operate,depending tongue mechanism engaging with the grooves 9 in the car-doorsto assist in positioning such doors and in vsealing' the joint betweenthe same and the frame of th'e car, androclcsha'ft and; chain mechanismfor opening and closing such doors, substantially as described.

5.V Ina car of the class described, the comi 4binarios of asupporting-framework provided with center sills transverse deck-beamsand 5 vertical sidev and end boards, a dumping b ottom portion formed ofa plurality of -swingn ing doors arranged between the transversedeck-beams 'at each side of the longitudinal center of the car andpivoted to the frame thereof at theirinner edges and provided with agroove or grooves at or near their free edges, x1 and a plurality ofchannel-beams straddling the transverse .deck-beams of the car withtheir lower depending -edges engaging the grooves in the swinging doorsof' the bottom portion to assist in positioning the-same and n insealing the joint between such swinging4 doors and the car-tframe,substantially as described.
